This model is discontinued
AirTAC has phased out the MAL series. The drop-in replacement is ACED50X175B — same bore, stroke, output force, port and mounting, so it fits the same application. Simply order the ACED50X175B in place of this model. The ACE replacement is a current-production ISO 21287 compact cylinder in the same bore, stroke and force class, with a matching short body and the same mounting-accessory family, so it fits the same envelope. Confirm mounting-interface dimensions against the ACE datasheet before ordering.
Airtac ACPD Double Rod Compact Cylinder ACPD50X175B
The AirTAC Airtac ACPD Double Rod Compact Cylinder ACPD50X175B is a double acting, double rod DIN-standard tight/compact air cylinder with a Ø50mm bore and 175mm stroke, 1/8" air ports and a hard-anodized aluminium body. This model is discontinued — the current-production replacement is the ACED50X175B (ISO 21287 ACE), in the same bore, stroke and force class.

About the Airtac ACPD Double Rod Compact Cylinder ACPD50X175B
A double acting compact cylinder with a rod through both covers, the ACPD50X175B delivers 881.2 N in either direction at 0.5 MPa (1233.7 N at 0.7 MPa) because both strokes work on the rod-side area. The 16 mm through-rod resists rotation and side load, gives a symmetric mount, and the rear rod can carry a sensor flag. Its 175 mm stroke sits inside the 250 mm standard range for the 50 mm bore, so it ships as a catalog item.
The hard-anodized aluminium body with an S45C hard-chrome rod is an ISO 21287 short build that saves about 50% of the mounting length of an ISO 15552 profile cylinder, ideal for tight gantries and jigs. Fixed TPU bumpers pad both ends, speed runs 30-500 mm/s, and pressure spans 0.15-1.0 MPa (22-145 psi). At 0.5 MPa the 881.2 N rating translates to roughly 53 kg of usable vertical lift once you keep a 2:1 margin, so match the part weight accordingly. Note this model is discontinued: the current-production drop-in is ACED50X175, same bore, stroke and force class.

Specifications follow the official AirTAC ACP datasheet (now discontinued). The ACED50X175B (ISO 21287) carries the same bore/stroke/force class; confirm mounting-interface dimensions against the ACE datasheet before installation. Rod type: female thread (blank) or male thread (B). Thread options: PT (blank) / G.
Theoretical Output Force (Ø50mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 881 N |
| 0.7 MPa | 1234 N |
| Max (@1.0 MPa) | 180 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac ACPD Double Rod Compact Cylinder ACPD50X175B Is Used
Reciprocating transfer slide
The through-rod drives a workpiece carrier from both ends on a packaging line, with equal 881.2 N thrust in each direction at 0.5 MPa and no need for a mirrored second cylinder.
Clamp-and-flip fixture
On a machining cell jig, the rear rod carries a switch flag for end detection while the front rod presses a part, both strokes delivering 1233.7 N at 0.7 MPa.
Pusher on a narrow conveyor frame
The short ISO 21287 body, about 50% shorter in mounting length than an ISO 15552 profile cylinder, slots between conveyor rails where a full-length body cannot fit.
Replacing the Airtac ACPD Double Rod Compact Cylinder ACPD50X175B with the ACED50X175B
Size between bores: at 0.5 MPa the 40 mm bore gives 571.8 N while the 63 mm bore gives 1458.1 N, so the 50 mm at 881.2 N both ways covers the middle band. The B code gives a male rod thread (M10x1.5 female on the blank version) and the port is 1/8" PT. FA/FB flange and LB foot mountings bolt to the ISO 21287 face. This unit has no magnet, so CMSE or DMSE switches cannot be used; order the -S code if position sensing is needed. A plain double-rod cylinder drifts when air is lost, so add a rod lock or pilot check for a held load. Replace it with ACED50X175 and confirm ISO 21287 mounting dimensions before the swap.
Replacement checklist
- ✓ Current-production ACE → ACED50X175B
- ✓ Same bore / stroke / force class
- ✓ Confirm ISO 21287 mounting dimensions
- ✓ Port/thread type (PT / G)
- ✓ Add -S for magnet if you need sensors
Airtac ACPD Double Rod Compact Cylinder ACPD50X175B FAQ
Because a rod exits both covers, force is equal both ways: 881.2 N at 0.5 MPa and 1233.7 N at 0.7 MPa on the rod-side area, with a maximum of 179.7 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), speed 30-500 mm/s, and the 175 mm stroke is within the 250 mm standard range for this bore.
Only if the cylinder was ordered with the optional -S magnet; this ACPD50X175B has no magnet, so CMSE or DMSE switches cannot be fitted. The ACPD family is discontinued, and the current-production drop-in is ACED50X175 in the same bore, stroke and force class. Confirm the ISO 21287 mounting dimensions before swapping, since the ACP follows the older DIN-standard layout.
